Application filed November 3, 1920. Serial No. 421,524.

he simple in construction, easily assembled and susceptible of quantity production.

In the ordinary type of gas cook, the stop on the turning plug is formed by inserting a pin in an opening in the plug at the proper point. Sometimes this pin becomes loosened and drops out of place with the result that the plug may unintentionally be turned to Euch a position as to permit escape of the uid. A

One of the objects of my invention is to design a cock of this type, which will overcome this defect.

Another object of the invention is to design the parts of the cock so that they. may be die-cast, thus permitting of quantity production and eliminating the necessity of hand finishing orpolishing as in the case where the parts are cast in sand molds.

Another object of the invention is the design and location of the stop so'thatit will be invisible, the gas cook thus having a finished external appearance. I I

Another object of the invention is the location and protection of the stop, so that dirt will not accumulate and pack around it andkintejr fere with the proper closing of the coc With these and other objects in view, my invention consists of certain novel and peculiar features of construction and combination of parts as hereinafter described and claimed, and in order that it may be clearly understood reference is to be had to the accompanying drawing in which;

Figure 1 is an elevation of a gas cock,with a fragmentary section showing the stop arrangement;

Fig. 2 is a section of the line 2--2 looking in the direction of the arrows;

Fig. 3 is a plan view of the washer provided with the stop.

Referring to the drawings for a more complete disclosure of the invention, 1 is the barrel of the cock having a tapered turning plug 2 therein. The smaller end of'the plug is reduced in diameter to provide a shank Fitting over the shank is a washer which is keyed thereto in any suitable manner such as shown at 5. The shank is inter nally threaded to receive a screw 6 for hold ing the washer in adjusted position up against the end bearing 16 of the barrel of the cock, so that the plug is securely held from being withdrawn from its bearing.

For providing a means to limit the turning movement of the plug, the washer 4 isprovided on its inner surface with a stop 7. This stop may be and preferably is made integral with the washer. When made integral therewith it may be fabricated in large quantities bythe die-casting operation,

' or by stamping.

beyond its closed position through failure of the stop to operate as intended.

From the above description it will be apparent that I have produced a device of the,

character described which possesses all the features enumerated as desirable and while I have illustrated andldescribed the preferred form of my invention, it will be understood that I reserve the right to all changes properly falling within the spirit and scope of the appended claims.

While I have described the application 0 my invention in connection with a gas. cock, I do not intend to limit it solely to that use, but it can be applied to any valve of a similar type.

ll claim: 1. In a device of the character described, a rotary plug, a casing in which the pin rotates, a washer secured to the plug an provided with it etc on its inner face extendin parallel to t e axis of the lug and fixed s oulders on the inner side 0 the casing for cooperating with the said stop.

2. In a device of the character described,

- and a rotary plug, a casing in which the plug rotates, a washer secured to the plug and provided with a stop, fixed shoulders on the inner side of the casing for cooperating with the said stop, the flat face of the washer overlying and engaging the end of the eas- 1n v In a device of the character described, a rotary plug, a casing in which the plug rotates, a washer secured to the plug, a -stop extending parallel to'the axis of the plug interposed between the inner face of the washer and the inner side'of the casing to limit the turning movement of the plug.

4. In a device of the character described,

a rotary plug, a casing in which the plug r01 tates, a washer secured to the plug, and prorotates, a

vided with a stop on its inner face extending parallel to the axis of the plug, shoulders on the inner side of the casing for cooperating with the said stop, the said washer overlying and engaging the end of the casing.

5. In a device of the character described, a rotary plug, a casing in which the plug washer securedto the plug, a stop extendln parallel ,to the axis of the plug and inter osed between the inner face of the washer tilhd the inner side of the casing to limit the turning movement of the plug,,the said was er overlying and engaging the end so of the casing.

In testimony whereof I afiix my signature.
